Sorry for asking here, but got banned from the fitness sub last year.

I've recently started lifting again after a long hiatus, following the ice cream 5x5 program. I've been on it for about a month or so, maybe a little more. So far I am enjoying it, but my bench press is dragging along.

I weigh 205lbs and my bench sets today were to be done at 72kg (gym only has kilo plates). Failed.

My bench has always been terrible, even when I could squat 4 and deadlift 5, I could barely bench two plates, and I mean barely.

All of my other lifts have been progressing great. My squats are clean and each progression feels easy. Same with all other mains and accessories.

Why am I failing my bench progression of 2kg/session after only a month or so when all other lifts, including OHP, are progressing fine? Is this normal? Considering I've always been a shit bench presser, I don't know.

My sleep/diet are okay and to the best of my ability. I try to get 8 hours (10-6) every night but have chronic insomnia, and I'm in the Army so I eat as clean as possible at the chow hall (not allowed to cook in the barracks and can't afford pre-made food). No excuses, just how it is. Working on it.

Tips? I'm about to reset my bench and my OHP will probably be greater than my bench in the near future.
